    TBI + Megasquirt

    So I am wanting to add a little bit of tunability to the 400SBC, and was considering TBI like the 4.3s. There are some aftermarket TBI units that are almost a bolt on upgrade that I could use for better airflow, and it will be pretty easy to tune with a megasquirt system.

    So I actually started looking around for some info, and I found this article on the DIY Autotune website:

    Any thoughts, anyone running a setup like this with thoughts?

    Well first off, what are your specs of your engine, and are you going to do any more upgrades to it from there?

    There is a point where you just need to switch to a multiport setup, or at least a FOUR injector setup.

    Depending on how mild or wild you want to go the stock gm ecm's for tbi can be a very powerfull setup, im not going to elaborate tho until i know what your planning.
